Fine focus:
The smaller fine focus knob is
coaxial with the coarse focus, which means
they turn on the same axis. This knob allows
more precise image resolving after the
image has been brought into focus with the
coarse focus knob.

Illuminator:
The illuminator provides
necessary light underneath the stage. It
contains a 20-watt halogen bulb. Instructions
for changing the bulb are on page 6.
13.
Illumination intensity control:
This
control adjusts the intensity of the light
produced by the illuminator. It should be in a
low position when turning the illuminator on
or off. Use the iris diaphragm to adjust the
light for
contrast;
use the illumination
intensity control to adjust the light for
brightness and intensity.
Operating Procedure
Now that you have an overview of each
component on your microscope, you can follow
this step-by-step procedure to get started using
it.
Installing the Microscope Head
The microscope head is shipped in a
separate carton and will need to be installed.
Carefully remove the head from the packaging.
1.
Loosen the set screw located above the
nosepiece.
2.
Set the head firmly in place, making sure it’s
flush against the head support, and tighten
the set screw just enough to hold the head
in place.
3.
Rotate the head to desired position, and
then tighten the set screw to hold it securely.
MI-6000BIN Model
The MI-6000BIN model comes with a
Seidentopf binocular head for enhanced image
examination and extended viewing comfort.
Using the Binocular Head
To best use this feature, you must set the
interpupillary distance to match the distance
between your eyes’ pupils and adjust the
diopters to compensate for focusing differences
between your eyes. Each user must adjust it for
his or her own eyes. To do so, follow these
steps:
1.
Start by focusing a small specimen in the
center of the viewing field using the 10x
objective. The iris diaphragm should be in
the closed position.
2.
Focus your eyes on the specimen.
3.
Pull your eyes back from the eyepieces
about 1”. In your peripheral vision you will
see two field view circles overlapping each
other.
4.
Open or close the distance between the
eyepieces by pulling them apart or pushing
them together until the two circles merge
together and appear as one circle. The
interpupillary distance is set correctly when
you see just one field view circle. Record the
settings so you can return to your
adjustment easily.
5.
Turn the nosepiece until the lowest power
(4x) objective clicks into place.
6.
Holding a card over your right eye (the eye
in front of the eyepiece with the diopter)
bring the specimen into focus for the left eye
using the coarse and fine focus controls.
7.
Cover your left eye with a card and bring the
specimen into sharp focus for your right eye
by turning the knurled diopter band on the
right eyepiece. Do not use the coarse and
fine focus controls for this last step – use
only the diopter adjustment.
Getting Started
